Object of the Week: Incandescent Light Bulb in Display Case, Joseph Swan (maker), London, England, about 1877. 2018.8.6. The incandescent light bulb was not invented by a single person. One of the early makers of light bulbs was Joseph Swan, who received a patent in 1860 for a low-quality, brief-lifetime incandescent light bulb. He improved this initial design in 1875 and 1880 by fabricating a carbonized thread filament and improving the vacuum in the bulb. The early date of this bulb identifies it as one of the world’s oldest surviving examples of the light bulb. -- source link
